What is Chatwoot?

Chatwoot retires Captain V1 and rebuilds its AI assistant as a structured, per-assistant behavior system.

Chatwoot is in the middle of a significant architectural transition for its AI assistant layer. The original Captain V1 (free-form instructions) is being retired in the next self-hosted release in favor of a structured model with scenarios, response guidelines, guardrails, and a testing playground. Cloud users are already on the new system. Alongside this, two substantial releases expanded Captain's control surface: per-assistant custom tools, inactivity handling, and audience/schedule targeting. WhatsApp BSUID support and improved call recording controls round out a busy month in the communications layer.

What is Dovecot?

Dovecot's 2.4 branch is being hardened release by release after a breaking rewrite.

Dovecot is the IMAP and POP3 server behind a large share of the world's mailboxes. The 2.4 branch opened in January 2025 with a deliberately incompatible release — configuration files must be rewritten, the plugin section is gone, and several long-standing features were removed outright — and every release since has been consolidation on top of it. The pattern is consistent: each point release leads with critical CVE fixes, then lists incremental changes. The latest, 2.4.5, carries twelve CVEs alongside post-quantum ML-KEM support, full-text phrase searching and a throttling response code.

Chatwoot vs Dovecot: editorial side-by-side

C7.5

Chatwoot retires Captain V1 and rebuilds its AI assistant as a structured, per-assistant behavior system.

◆ Current state

Chatwoot is in the middle of a significant architectural transition for its AI assistant layer. The original Captain V1 (free-form instructions) is being retired in the next self-hosted release in favor of a structured model with scenarios, response guidelines, guardrails, and a testing playground. Cloud users are already on the new system. Alongside this, two substantial releases expanded Captain's control surface: per-assistant custom tools, inactivity handling, and audience/schedule targeting. WhatsApp BSUID support and improved call recording controls round out a busy month in the communications layer.

◆ Where it's heading

Chatwoot is shifting Captain from a chatbot add-on into a proper automation layer with auditable, testable behavior. Per-assistant tool isolation, audience segmentation, and schedule-based availability bring it closer to the model used by Intercom Fin and Zendesk AI. The V1 retirement removes a backward-compatibility constraint that was slowing this transition. The playground — which lets admins test assistant configurations before saving — removes the need to test in production, which was the practical barrier to iterating on Captain.

◆ Prediction

The next likely move is a reporting layer for Captain — tracking resolution rates, handoff rates, and scenario effectiveness per assistant. The playground's 'Run details' view (showing which scenario handled a message and which tools ran) is the building block for that kind of analytics.

2.5

Dovecot's 2.4 branch is being hardened release by release after a breaking rewrite.

◆ Current state

Dovecot is the IMAP and POP3 server behind a large share of the world's mailboxes. The 2.4 branch opened in January 2025 with a deliberately incompatible release — configuration files must be rewritten, the plugin section is gone, and several long-standing features were removed outright — and every release since has been consolidation on top of it. The pattern is consistent: each point release leads with critical CVE fixes, then lists incremental changes. The latest, 2.4.5, carries twelve CVEs alongside post-quantum ML-KEM support, full-text phrase searching and a throttling response code.

◆ Where it's heading

Two things are being worked at once. Security is the visible half, and the volume is striking — resource-exhaustion and parser issues in IMAP THREAD, LIST and ID, a CRIME-style compression side channel, an authentication bypass through XCLIENT forwarding. The quieter half is that fixes are increasingly gated behind version declarations: the THREAD fix needs a new index format enabled only by raising dovecot_storage_version. That mechanism, introduced with 2.4.0, is now doing real work, letting operators take format changes on their own schedule.

◆ Prediction

Experimental flags for mail UTF-8 and IMAP4rev2 have carried unchanged through every 2.4 release so far; the next branch-defining move is one of those graduating to default rather than another security round.
